Does anyone have any experience with metal detector circuits ?
I have a circuit for a BFO type detector but have read that this
design is quite old and that 'pulse induction' designs are considered
far better.
I also have a design for a detector which uses a faraday shield on the
coil. The design states this has to be constructed using 'tin' foil,
and not 'aluminium foil'. Is this correct ?
Any circuit ideas would be appreciated.
Thanks
